All you have to do is THIS: They are talking about your going into the directory structure and creating the path and file that the installer is looking for: C:Program files (x86)/Common Files/Daz/dzinstall.ini.

You would do this using "My Computer" and just navigate into Common files, create a Daz folder (if it's not there) and inside that folder, create an empty file called dzinstall.ini by right clicking in that directory and using the "New File" option.

I had same problem today and Basicwiz helped me out..It works like a charm.
